Which two components are encompassed by FANS 1/A+?

• A. GPS + ADS-C
• B. CPDLC + ADS-B
• C. CPDLC + ADS-C
• D. CPDLC Alone

Answer: (C)

FANS 1/A+ combines data-link control with automated surveillance for oceanic and remote airspace. The two essential elements are CPDLC, which handles text-based controller-pilot communications for clearances and routing, and ADS-C, which provides automated position and related data to ATC under predefined reporting contracts. Together, they enable efficient, reliable operations where radar and voice VHF/UHF communications aren’t available. GPS is just a navigation reference, not a data-link or surveillance component, and ADS-B is a separate surveillance technology. CPDLC alone would lack the required surveillance capability, so pairing CPDLC with ADS-C best matches what FANS 1/A+ encompasses.
